ANTON AU, OF CRANDON, SOUTH DAKOTA.

SCRUBBING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 524,751, dated August21, 1894.

Application filed April 28, 1894. Serial No. 509,380. (No model.)

To aZZ whom it may concern.-

Be it known that I, ANTON AU, a citizen of the United States, residingat Orandon, in the county of Spink and State of South Dakota, haveinvented certain new and useful Improvements in Floor-ScrubbingMachines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to machines which are used for scrubbing floors,and its objects are to revolve a brush or series of brushes bearmg uponthe floor; to deliver clean water ahead of the brush; to gather up thedirty water behind the brush and to wipe the floor soas to quickly cleanand dry it.

To these ends my invention consists in the construction and combinationof parts formlng a floor scrubbing machine, hereinafter described andclaimed, reference being had to the accompanying drawings, in which-Figure I, is a side elevation of a scrubbing machine according to myinvention, certain parts being broken away. Fig. II, is a top view ofthe same.

5 represents the frame of the machine mounted to travel on a pair ofwheels 6 at its forward end, and provided with handles 7, by means ofwhich it may be propelled and guided around over the floor.

8 represents the scrubber consisting of a head mounted upon a shaft 9'which is journaled vertically in bearings in the frame. This scrubbermay have a single brush, or it may be provided with a number of brushes10, fixed radially or in any slanting position desired upon the lowerface thereof.

11 represents a tank for carrying clean water. It is removably locatedin the forward part of the frame and provided with a. faucet 12 arrangedto deliver water in front of the scrubber. This faucet may be set so asto drip the water slowly or it may be left farther open to deliver morewater according as it may be required.

13 representsa mopping belt made of thick material adapted to soak upwater. It is mounted upon the drum 14 and a pulley 15 to be rotatedrubbing upon the floor against the direction of travel of the machine.

16 is a trough located with one edge bearin g closely against themopping belt to scrape therefrom the surplus water and the-free dirtcarried thereby. This trough slants a little .to one side and isprovided with a delivery spout 17 at that side to convey the dirty.water into a tank 18. This tank is provided with a bail 19 whereby itmay be drawn out from the frame and carried away to be emptied.

20 is a hand crank whereby both the scrubber and the mopping belt arerotated in service. This crank is mounted upon a shaft 21, which isprovided with a gear wheel 22, adapted to engagea gear wheel23, onanother shaft 24, upon which is mounted a beveled gear 25, which engagesa beveled gear 26 on a vertical shaft 27.

28 is a gear wheel fixed upon the shaft 27 and connected with a pinion29 on the scrubber shaft 9 by means of an intermediate gear wheel 30.

31 is a sprocket wheel mounted upon the shaft 24, and 32 is a chainconnecting this wheel with a sprocket wheel 33 which is fixed to theshaft of the drum 14. The shaft 9 is fitted to slide vertically in itsbearings, and 34 is a spring pressing upon its end to impel the brushesdownward upon the floor while at work. I

35 is a shifter connected with a groove in the shaft 9 and provided withalever handle 36 whereby it may be raised to lift the scrubber entirelyfree from the floor when the machine is being rolled from place toplace, and 37 is a latch adapted to engage an upward facing notch 38 inthe frame to hold the scrubber raised. i

39 is a downward facing notch which may be engaged by the same latch tohold the lever 36 and the scrubber down when it is desired to press veryhard upon the'floor.

The tank 11 is provided with a convenient lid 40, and with a bail 41whereby it may be carried to be filled.

42 is a fender made of sheet metal and located around the scrubber at alittle distance therefrom, where it is held suspended from the frame toprotect the mop-board and other objects which the scrubber may pass bywhen at work, from being spattered.

43 represent buttons on the frame project- 7 ing over the edges of thetank 11 to retain it in place. The mopping belt may be of one or morethicknesses of any absorbent material suitable for this purpose.

The pinion 29 is vertically elongated in order that it may continue toengage the. intermediate gear wheel 30 whether the scrubber be raised orlowered while in operation.

The absorbent nature of the mopping belt 13 tends to soak up the waterand by being revolved to rub upon the floor against the direction oftravel of the machine,its tendency is to rub the floor clean and leaveit entirely free of standing water.

The trough 16 hanging from pivots 44 and further pressed by a spring 45bears against the face of the mopping belt enough to press it somewhatout of line thereby serving as a 1 scraper to strip off any looseparticles which may be picked up by the belt, and to squeeze out thedirty water therefrom.

In operating this machine it may be stood over any particularly dirtyspot and there the brushes may be revolved as long as required to do thecleaning.

By bearing much or little on the handles the mopping belt may be rubbedhard or lightly upon the floor.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. The combination in a floor scrubbing machine, of a brush mounted on avertical shaft in a frame and means for rotating it; a shifter connectedwith the shaft; an operating lever for the shifter; a reversible latchon the lever and notches in the frame facing upward and downward to beengaged by the latch, substantially as describe I 2. The combination ofa floor scrubbing machine frame mounted on wheels; a water tank having adelivery faucet at its front end; a scrubberobehind the tank delivery; amopping belt mounted to rub on the floor to the rear of the scrubber;ascraping trough hung to bear against the belt and a spring actingthereon, a delivery spout from the trough; a tank to receive dirty waterand means for operating the machine, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ANTON AU.
